Bug #45914	Restore errors if there is a privilege on a quoted database name
Submitted:	2 Jul 15:55	Modified:	11 Aug 14:42
Reporter:	Jorgen Loland
Status:	Duplicate
Category:	Server: Backup	Severity:	S3 (Non-critical)
Version:	5.4.4	OS:	Any
Assigned to:	Chuck Bell	Target Version:
Triage:	Triaged: D1 (Critical)

Description:
Restore errors if a backup image contains a privilege on a database who's name is in
quotes:

CREATE DATABASE `my-database`;
CREATE USER joe;
GRANT SELECT ON `my-database`.* TO joe;

BACKUP DATABASE `my-database` TO '1.bup';
DROP DATABASE `my-database`;
RESTORE FROM '1.bup';
### Errors

How to repeat:
> CREATE DATABASE `my-database`;
> CREATE USER joe;
> GRANT SELECT ON `my-database`.* TO joe;
> BACKUP DATABASE `my-database` TO '1.bup';
backup_id
276
> DROP DATABASE `my-database`;
> RESTORE FROM '1.bup';
ERROR HY000: Could not execute grant '`my-database`.`<empty> 1`'.
> SHOW WARNINGS;
Level	Code	Message
Error	1064	You have an error in your SQL syntax; check the manual that corresponds to
your MySQL server version for the right syntax to use near '-database.* TO 'joe'@'%'' at
line 1
Error	1751	Could not execute grant '`my-database`.`<empty> 1`'.
Warning	1776	Operation aborted - data might be corrupted

Suggested fix:
Restore needs to succeed.

Cannot repeat. Creating regression test case. Will submit a patch that contains only the
test case.

A patch for this bug has been committed. After review, it may
be pushed to the relevant source trees for release in the next
version. You can access the patch from:

      The bug can no longer be repeated. This patch adds a regression
      test case to ensure the problem doesn't return.
     @ mysql-test/suite/backup/r/backup_objects.result
        Result file with new test case.
     @ mysql-test/suite/backup/t/backup_objects.test
        Added test that case executes backup and restore of a database using
        quoted name and privileges assigned to a user.

Good to push.

It has been revealed that BUG#43444 fixed this problem and a test case was included in
that patch. Thus, this has been solved by BUG#43444.
